Ingalls is the third municipal water treatment
plant for which an ozone system was designed and supplied
by CleanWater Ozone. The town water is supplied by wells,
pumping at a rate of 1250 GPM. Iron levels ranged between
2.5 and 3.5 ppm; manganese was 0.05 ppm; iron bacteria
was also present in the water. High chlorine injection
was unable to oxidize the iron and manganese.

The CleanWater Ozone system was equivalent
in cost to an aeration/detention system. A pilot study
had been conducted over a period of 12 months prior to
installation to demonstrate to the Indiana Department of
Environmental Management (IDEM) that our ozone system would
operate efficiently using filtration at the rate of 10
GPM per sq. ft.; based on the success of this study, IDEM
granted CleanWater a variance to its 10-state standard
of 3 GPM per sq. ft. Click

This represents a substantial cost saving to our municipal
clients.

The ozone system has been operating successfully
at Ingalls since its installation. The iron content in
the wet well varies from 0 to 0.05 ppm; the removal of
organics and bacteria leaves the water crystal clear, with
the taste and appearance of bottled water.
